TypeTupletoArgTypes_sysv_x64(Typet);

This breaks a type down into 'simpler' types that can be passed to a function in registers, and returned in registers. This is the implementation for the x86_64 System V ABI (not used for Win64), based onhttps://www.uclibc.org/docs/psABI-x86_64.pdf.

Parameters:

Typet type to break down

Returns:

tuple of types, each element can be passed in a register. A tuple of zero length means the type cannot be passed/returned in registers. null indicates avoid.
